  • Exploitation of the ocean's deep water has brought humanity a wealth of treasures for centuries. Even so, it can confidently be forecast that the Ocean will be far more important to future generations than it has ever been in the past. Although many researchers endeavor to explore oceans, the ocean holds the crucial elements for maintaining a growing industrialized population in search of raw materials. This requires careful study and selection of innovations that will provide future generations and raw materials with an unlimited renewable and non-pollution energy and raw materials source with advantageous side benefits.

  • The dc reactor type superconducting fault current limiter is composed of a power converter, magnetic core reactors and a do reactor that is a superconducting coil. When a fault occurs, the dc reactor maintains the stability of system by limiting its fault current. In this study, we focus on the design of the dc reactor using FEM(Finite Element Method). In order to design it, various elements should be considered such as magnetic field intensity, Lorentz's force, its inductance and so forth. Firstly, we forecast the values of those elements from the simulation of FEM and then measured with a copper wire magnet. Finally, verify the reliability of this FEM method by comparing with two results.

  • In engineering hydrology, an estimation of precipitation loss is one of the most important issues for successful modeling to forecast flooding or evaluate water resources for both surface and subsurface flows in a watershed. An accurate estimation of precipitation loss is required for successful implementation of rainfall-runoff models. Precipitation loss or hydrological abstraction may be defined as the portion of the precipitation that does not contribute to the direct runoff. It may consist of several loss elements or abstractions of precipitation such as infiltration, depression storage, evaporation or evapotranspiration, and interception. A composite loss rate model that combines four loss rates over time is derived as a lumped form of a continuous time function for a storm event. The composite loss rate model developed is an exponential model similar to Horton's infiltration model, but its parameters have different meanings. In this model, the initial loss rate is related to antecedent precipitation amounts prior to a storm event, and the decay factor of the loss rate is a composite decay of four losses.

  • The duration of a construction project is not only a key element for taking a new order, but also a strict yardstick to determine certain project successful or not. However, since construction project is basically outdoor job and most of the activities are proceeded out-air, no matter how the schedule plan has been established accurately, actual project proceeds due to the weather condition, beyond anyone's control. In this paper, the functional relationship between work productivity rate and weather elements is suggested by regression analysis. Difference of the relationship and influence of weather due to the seasonal group are also revealed. With these results, by simulating actual weather data and generating weather forecast through historical data, more accurate schedule would be obtained.

  • The article reflects short-term perspectives on the use of information and communication technologies in the training of teachers for higher education. Education is characterized by conservatism, so aspects of systematic development of the industry are relevant to this cluster of social activity. Therefore, forecasting the introduction of innovative elements of ICT training is in demand for the educational environment. Forecasting educational trends are most relevant exactly in the issues of training future teachers of higher education because these specialists are actually the first to implement the acquired professional skills in pedagogical activities. The article aims to consider the existing potential of ICT-based learning, its implementation in the coming years, and promising innovative educational elements that may become relevant for the educational space in the future. The tasks of scientific exploration are to show the optimal formats of synergy between traditional and innovative models of learning. Based on already existing experience, extrapolation of conditions of educational process organization with modeling realities of using information and communication technologies in various learning dimensions should be carried out. Educational trends for the next 3 years are a rather tentative forecast because, as demonstrated by the events associated with the COVID-19 pandemic, the socio-cultural space is very changeable. Consequently, the dynamism of the educational environment dictates the need for a value-based awareness of the information society and the practical use of technological advances. Thus, information and communication technologies are a manifestation of innovative educational strategies of today and become an important component along with traditional aspects of educational process organization. Future higher education teachers should develop a training strategy taking into account the expediency of the ICT component.

  • 고층건물의 해체공사는 멀지 않은 장래에 급속도로 증가할 것으로 예상되며, 이들의 일반적인 해체방법은 기계식해체공법과 발파해체공법으로 대별할 수 있다. 해체공법의 결정은 해당건물이 가지는 지리적, 환경적 요인에 따라 많은 변동요인들이 있지만 일상적인 경우라면 경제성 판단이 공법선정의 가장 중요한 요인으로 작용한다. 따라서 본 연구에서는 다른 해체공법 선정요인들 보다는 객관적인 비교가 가능한 도심지 고층건물의 해체비용을 기계식공법과 발파공법으로 구분하여 산출하였으며, 이것의 비교 분석을 통하여 발파해체공법의 향후 활성화 시점을 전망하였다.

  • In this study, the use survey of domestic and international weather information on coastal regions and the demand survey (e.g. general and in-depth surveys) for customer needs with coastal industries were carried out to design customized coastal weather contents. The general demand survey showed that most of the customers working in the coastal industries were interested in a short-term forecast, such as a general weather outlook (approximately 29% of the total respondents) and typhoon information (19%), and they preferred to be given the forecast information from new media such as the internet web-pages (36%) and mobile utilities (23%) rather than old media such as TV (16%) and radio (11%). In addition, only 31% of the total respondents were found to be satisfied with the use of the current coastal weather service. This low percentage might mainly be a result of lack of information accuracy (about 64%) and diversity (28%). From in-depth survey with site visiting, the need of coastal weather contents, such as weather elements, data form, a tool of communication, and forecast interval, differed with the working stages in three coastal industries (e.g. shipbuilding, maritime trade, and passenger transport industries).

  • The purpose of this study is to analyze the aesthetic characteristics of PRADA's sports fashion, leading the fashion trend and one of the most influenced designers in 1990's, and thereby, helps to forecast them in the future. We studied the concept of sports fashion and the historic background of PRADA sports fashion. We also used corroborative method resolving Internet illustrated magazine, fashion journals and magazines so as to analyze the aesthetic and formative features from 1990's up to now. The results were summarized as follows ; The sports fashion in 1990's was classified into functional sportswear and town sports look. The functional sportswear can be separated into active sportswear and street sportswear. Town sports look that has been combined the elements of design in active sportswear had characters slim silhouette and simple details influenced by minimalism and reflected on the mainstream of 1990's lifestyle. Especially, PRADA's town-wear using high-tec textiles for sportswear affected on other couturiers and settled down them in the world wide fashion trend with her aesthetic expression. The aesthetic characteristics of PRADA's sports fashion appear the zenith of the minimalism and the elements of postmodernism which expressed remarkably the advanced future and familiar past at the same time as like high-tec materials, and classic silhouettes with functional details. Finally, we are able to anticipate that the aesthetics of PRADA sports look will be continued in the 21C with concerning about well-being, health, and sports & leisure.

  • This study aims to empirically analyze the relationship between climate change elements and catch amount of coastal fisheries, which is predicted to be vulnerable to climate change since its business scale is too small and fishing ground is limited. Using panel data from 1974 to 2013 by region, we tested the relationship between the sea temperature, salinity and the coastal fisheries production. A spatial panel model was applied in order to reflect the spatial dependence of the ocean. The results indicated that while the upper(0-20m) sea temperature and salinity have no significant influence on the coastal fisheries production, the lower(30-50m) sea temperature has significant positive effects on it and, by extension, on the neighboring areas's production. Therefore, with sea temperature forecast data derived from climate change scenarios, it is expected that these results can be used to assess the future vulnerability to the climate change.

  • The purpose of this study is to demonstrate the relationship between the results of the analysis of the overseas railroad station buildings, which was conducted using the factors of environmental cognition for the purpose of designing an interior environment for the Incheon International Airport Railroad station that will be newly constructed, and the plan that could be applied to the design of interior environment for the airport railroad station. The station with a complex interior space layout and relatively larger space tends to be difficult to predict or forecast passenger's needs or recognition element in approaching stage of intoner environment design since the human's biological memory system is greatly affected by such factors. Cognitive approach at empirical standpoint would possibly create the design, of which elements will Implement the functions of their own as such approach enables necessary information to be structured in a systematical way and manner In implementing interior environment design for such stations to be built for the first time in Korea, behavioral approach based on systematic theory proved to be very crucial. Under such a background, the study was aimed at extracting the assessment elements for interior environment design, then setting the frame of cognitive approach to eventually propose the guideline in approaching to interior environment design.
